SeqMode description

Sequence repeat counter

For each parameter set one can define an image repeat counter. Using the
image repeat counter means that a parameter set can be used for n consec-
utive images before the next parameter set is applied.

Setting the ImageRepeat field to 0 has the same effect like setting this field
to 1.

Manual stepping & reset

A sequence can be stepped further with a software command. To use manual
stepping use stepping mode 0x82 or 0x84, but don’t setup any input pin for
external sequence stepping.

Every time the PerformStep flag is set the sequence will be stepped one
parameter set further. Manual stepping observes the repeat counter also.

For some application it could be useful to reset the sequence during runtime.
Simply set the PerformReset flag to one: the sequence starts over with the
very first parameter set.

Sequence mode

Description

0x80

This mode is the default sequence mode and stepping
the sequence is compatible to e.g. the Marlin series.
With each image integration start the sequence is
stepped one item further and the new parameter set
becomes active for the next image.

0x82

Stepping of the sequence is controlled by a rising edge
of an external signal. The new parameter set becomes
active with the next integration start. When using this
mode select the suitable input mode of the input lines.

0x84

Stepping of the sequence is controlled by a high level
of an external signal. The new parameter set becomes
active with the next integration start. When using this
mode select the suitable input mode of the input lines.

Other mode

Choosing any other mode value, automatically defaults
to mode 0x80.

Note

It is also possible, that a sequence consists of parameter
sets with different sequence modes. This can be achieved
by using the SeqMode and the ImageNo fields within the
Sequence_Param register.
